Returns the list of available devices and their capabilities for the QCanBusDevice .

errorMessage contains an error description in case of failure.

[pure virtual] QCanBusDevice *QCanBusFactory:: createDevice (const QString & interfaceName , QString * errorMessage ) const

interfaceName is the CAN interface name and errorMessage contains an error description in case of failure.

如果工厂不能创建插件，它返回 nullptr .
